I went to the Biteki site you provided in an older post with a collection of Christmas releases, and there was an Aube mosaic palette listed on page 13 which I cannot find anywhere?? Could anyone else find this?

I think the Mosaic Powder is available in the shops but for some strange reason, it's not featured on the Aube website. It's not just Aube that does that. Sometimes the limited edition items from Maquillage are also not featured on the website at all but can be easily found in the shops.
